i am just getting into motocross and want a good bike thats cheap. i have been riding since i was 8 and now i am 16 6' tall and 270 pounds (all muscle lol jkjk) and i was wondering if the YZ125 would be a good choice. i have ridden many sizes of bike but the 125. i have raced with one on trails and it seems like it would haul my fat ... around. im low on cash and the 2000 YZ just seems like the bike to get. its either a YZ250F or 125. should i get the 125 learn the 2stroke way get a feel for motocross then get the 250?
